Notes to Specifications

Specifications

1. Tested at each output.

2. Parameter guaranteed byline and load regulation tests.

3. Although operation with no load is permissible, light loading on the main (+5V) output may cause the output voltage of the auxiliary

outputs (

±12V or ±15V) to drop out of regulation. It is therefore recommended that at least 100mA or 20% of the output power,

whichever is greater, be taken from the main (+5V) output and at least 50mA (or

±12V: 1.2W, ±15V: 1.5W) of the output power is

taken from the auxiliary (

±12V or ±15V) .

4. Total combined output power –30W.

5. Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.

6. An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the overload protection

circuit and is the condition of maximum power dissipation.

7. Load step transition time between 2.0

µs and 10µs.

8. Recovery time is measured from the initiation of the transient to where V

9. Input step transition time between 2.0

µs to 10µs.

10. Parameter shall be tested as part of design characterization and after design or process changes. Thereafter parameters shall be

guaranteed to the limits specified in the table.

11. Turn on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the

inhibit pin (pin 8) while power is applied to the input.
